MOLD FOR CASTING CONCRETE "WALLS WITH A TILE FACING.

Application filed Gctober 23, 1911, Serial No. 656 224.

To all whom it may concern:

Be it known that 1, CHARLES O. ELLERT, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a new and Improved Mold for (lasting Concrete lValls with a Tile Facing, of which the following is a full, clear, and exact description.

My invention relates generally to molds for plastics and more particularly it is directed to an improvement in a mold con struction whereby wall facing elements may be positioned for engagement with the plastic when poured.

My invention is especially adapted for use in connection with the mold structure described and claimed in my (Jo-pending application, Serial No. 636,363, filed July 1, 1911, renewed Dec. 17, 1915 as Serial No. 67,487.

The principal object of my invention is to provide an improved form of mold constructed and arranged to hold wall facing elements in juxtaposition thereto by means of suitable clamping devices, a portion of each device, after the plastic has set and the mold boards have been removed, being left embedded in the wall and serving as a re inforcement thereof.

A further object of my invention is to provide an improvement in molds, especially adapted for use in connection with the mold described in my copending application hereinbefore mentioned, the mold boards sustaining wall facing elements on their inner sides by means of suitable devices, the plastic being poured between the mold board at the opposite side and the back of the facing elements whereby when the removable securing means between the mold boards and the facing elements is removed and the outer section is taken down, the wall will be faced with the said elements, parts of the securing means being left in the wall as a reinforcement thereof.

, Other objects. and advantages of my invention will appear'as the description of the different forms thereof proceeds, all of which are included within the scope of the appended claims.

Reference is to be had to the accompany- 7 ing drawings forming a part of this speci fication, in which similar characters of ref- Patented Aug. 1, 1916.

erence denote corresponding parts in all the vlews, and in which Figure l is a side view of my improved mold, portions of the outer boards being broken away in order to show the interior structure; Fig. 2 is a vertical sectional view thereof; Fig. 3 is a vertical sectional view of the finished wall withthe mold removed; Fig. 4 is a vertical sectional view showing a different form of mold facing, together with means for securing the parts together, Fig. 5 shows a further modification; Fig. 6 illustrates a structure wherein the facing of the mold is made up of succeeding series of slate; Fig. 7 is a sectional view of a modified form of mold and means for holding the facing thereof in position while the plastic is being poured; Fig. 8 is a perspective View of the holding means shown in Fig. 7 Fig. 9 is a perspective view of one of the elements of the facing used in the structures illustrated in Figs. 1 to 4 inclusive. I

As particularly pointed out and claimed in the co-pending application referred to, the mold is made up of standards 1 which extend preferably in a vertical direction, together with a plurality of mold boards 2, there being a plurality of shims or fillers 3 positioned and secured between the mold boards 2 and each of the standards 1; it is to be noted that the width of each shim is equal to that of a form board or a number thereof. Each of the standards is provided with a series of slots 4; through which suitable securing means 5 pass into engagement with the mold boards 2 whereby the mold boards, fillers and standards are firmly and securely held together. i

As shown in the drawings, the mold is positioned on top of part of the finished Wall or foundation 100, the lower ends of the standards being secured thereto by means of transversely extending securing means, such as bolts 6, the upper ends of the standards being positioned by means of the longitudinally extending member 7 which is especially adapted to'support a number of vertically extending reinforcing rods 8, the member 7 being secured to the standards through the medium of angle irons 9 and bolts or other securing devices 10.

The structure described and claimed in this application is directed particularly to the wall and serving 7 as a reinforcement thereof.

Referring particularly to Fig. 2, the arrangement of the standards 1 and the fillers 3 and mold boards 2 at the right hand side or back of the mold is similar to that set forth in my co-pending application hereinbefore mentioned. The left hand side or front of the mold is made up of the standards 1, together with the fillers 3' and'the mold boards 20 with the facing elements 21carried thereby. The mold boards 20 may be similar to the moldboards 2 at the back of the mold or they may be varied in some details of construction in order to provide forsecuring the elements 21 to the inner side thereof. As shown particularly in Fig. 2 the height of each of theelements 21 is less than the width of two of the mold boards 20, the difference being provided in order that a longitudinally extending supporting member 22 may be positioned between adjacent ends of facing elements, there being longitudinally extending holding device 23 having shoulders 24 thereon in engagement with the inside of the supporting member and the shoulders 25 present on this form of facing element. The mold is set up in position on top of the foundation or finished wall 100, the left hand side of the mold being the front and the elements 21 are placed adjacent the boards 20 with the supporting member 22 between them, the elements being held in position by suitable securing means, such as bolts 26 which pass through the supporting member and the holding device as well as through the mold boards and preferably between them, the inside of the bolt being provided, if so desired, with a nut 27.

WVith the parts in the position described the plastic is poured into the mold and when hardened, the mold boards may be removed by first removing the securing devices 5, after which the fillers or shims 3 may be 1 taken out, the removal of these parts permitting the mold boardsto be pulled away from the facing elements and entirely removed. The securing devices or fastening means 26 which secure the inner sections in position are .also removed, the holding device 23, together with the nuts 27, being left behind in the wall and serving as a reinforcement thereof; the supporting device 22 may also be removed, the finished ing device 23 may be made of any suitable material and in the event that the facing elements 21 are made of tile or similar substance, these supporting members will preferably be made of the same material so that in the finished wall structure the facing will be uniform throughout. Of course the openings or holes left in the holding device 23 and through which the securing or. fastening bolts 26 pass may be subsequently filled up. One of these elements 21 is set forth particularly in Fig. 9; it is there shown provided with a series of horizontally extending grooves 30 and spaced vertically extending grooves 31 in order to give the appearance of a brick structure,although it is obvious that the outer face of each of these elements may be provided with any suitable design whereby different forms and sizes are provided. V

In Fig. i I have illustrated a mold somewhat similar to that shown in Fig. 2, the modification residing in the fact that each of the facing elements 21 are of the same height or width as the mold boards 30, such an arrangement presenting a finished wall structure wherein the elements 21 thereof.

are closely adjacent with no removed pore tions or channels between them, such as is shown in Fig. 3; securing or fastening devices 26 may be used in this structure, these devices passing between the shoulders 25 of adjacent elements the inner end of the fastening or securing device being in engageremoved.

In Fig. 5 the facing elements are made up of a series of bricks 21 suitably positioned with respect to one another, and held adjacent the mold boards 20jby the securing means 26 which are clamps or equivalent devices similar to that already described, the inner end of the securing means being provided. with a transversely extending bar 23'. which is of sufficient length to engage a number of the bricks or tile so that they will be held secured in position when the plastic is being poured into the mold. Of course these transversely extending bars 23 and the nuts or equivalent devices 27 on the inside of the fastening means 26 are left in the finished wall'serving as a reinforcing means thereof,

when the form boards are removed, the finbricks or tiles of suitable design and of any convenient dimensions.

In some cases it may be desirable to have the finished wall faced with slate, successive rows of which are arranged in clapboard fashion and to this end I have illustrated means in Fig. 6 whereby such may be ob tained. The mold boards 20 have suitable blocks 2O" positioned between them, each of these blocks being provided with an inner and preferably rubber-faced shoulder 40 against the top of which the facing elements 23 are adapted to rest, being secured in such position by engagement with the upper end 23 of an adjacent element 23 there being a fastening device 26 similar to that already described passing through the block 20 and the upper end 23 of the element 23 and having a nut or equivalent element 27 secured to its inner end, whereby the parts are held together. In order to provide for sufficient engagement of the elements 23 and the plastic I provide each of the elements with an inwardly extending hook -11 whereby they become firmly bonded. It is to be particularly noted that by using the shoulder 4L0 at the inner end ofthe blocks 20, which shoulder is preferably of Width equal to the thickness of each of the elements 23*, I provide a system of over-lapping units whereby the face of the finished wall is made up of overlapping elements, such as slate or tile. In this structure the removal of the outer sections 20 and the fastening devices 26, to gether with the blocks 20 through which these fastening devices pass, leaves the finished face surface of the wall, the opening or holes therein through which the fastening devices pass being subsequently filled up with any suitable cement or plastic.

In Figs. 7 and 8 I have shown a modified form of means for holding the facing elements in position which in some respects is much simpler than those previously described inasmuch as the number of parts required for normal operation thereof is less ened. The left hand side of the mold is made up of the mold boards 20, similar to those described in my co-pending application hereinbefore referred to, the facing elements being made up of a series of vertically extending tiles of simple rectangular formation of any desirable material and outline, as well as size. These elements are placed one above the other closely adjacent the inside of the mold boards 20 and are held in such position by the following means. Secured adjacent the top of the mold is a longitudinally extending member 50 having a series of vertically extending openings therein through which wire members are rotatably mounted, each member being made up of the vertically extending portion 51 and the horizontally extending portion 52, the inner ends of the portions 52 being connected to a rod 53; suitably positioned along the member 50 are blocks 54 having openings therein across which a pin 55 extends,each of these pins being adapted to be engaged by a hook 56 which passes through the mold boards 20 whereby the parts are firmly held in position, as shown in Fig. 7. The distance between the vertically extending portions 51 and the inside of the mold boards 20 is substantially equal to the thickness of the elements 21 so that these portions 51 bear against these elements with a certain pressure, whereby they are held in position. As the plastic is poured into the mold and be gins to harden, the rod 53 may be moved back and forth, thereby rotating the portions 51 within the plastic so that they will not adhere theretoin the hardening process; when the plastic has been sufficiently tamped or-set to support the inner sections of the mold boards, the member 50 may be lifted, and with it the portions 51 and 52, and may be placed in position at a higher point in the mold, ready to engage the elements 21 which may then be added and placed in position before any more plastic is poured. As the wall increases in height this holding means for the inner sections is moved with it and when the wall is finished it may be entirely removed therefrom; the standards, and mold boards, together with the fillers, may be then removed and the finished wall has the facing elements secured thereto, there being no openings left in the facing or between any of the elements which go to make up the facing.

Of course the wires or rods 51 may be left embedded in the concrete and the member 50, or a number of such members, may be used to space and hold the rods or wires in position; the member 50 may be lifted when so desired, the rods 51 slipping through the openings therein, such a method leaving the rods or wires as a reinforcement within the finished wall.

From the above description taken in connection with the accompanying drawings it will be seen that I have provided a structure and several modifications thereof, any one of which is well adapted to perform the objects of the invention as stated in the beginning ef this specification; the size of the mold and the material of which the various parts are made may be widely varied, depending on the use to which the finished structure is to be put, such changes and modifications being included within the spirit and scope of the appended claims.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. A tile element mold comprising spaced uprights; mold walls supported by said uprights; and a tile or Wall facing supporting means, said means including a plurality of elements adapted to detachably engage one of said mold Walls, and a plurality of elements adapted to engage said first elements and the rear faces of said tiles or Wall facing.
